Abstract: A combustion enhancement device for internal combustion engines installed in front of the carburetor (or fuel injection pump) comprised of tourmaline crystal or mildly radioactive tritium isotope mineral elements. The tourmaline is directly utilized for the operation of a negatively charged ion generator that provides large volumes of negatively charged ions such that when air containing oxygen induced into the carburetor and the combustion chamber is thereby combustion-enhanced, a large volume of negatively charged ions is mixed with the large volume of positively charged particles naturally present in the air, enhancing combustion by purifying the oxygen required. As such, the power creating combustion of an internal combustion engine not only occurs at greater efficiency, but fuel is also combusted more completely, energy is saved because less fuel is required for combustion, and post-combustion exhaust emission density (especially of nitrogen oxides or NOx) is effectively reduced and improved.
